APPARATUS FOR DRYING FLOUR AND OTHER FINELY-DIVIDED SUBSTANCES.

Specification of Letters Patent No. 1,098, dated March 4, 1839'.

To all whom it may concern Be it known that We, JOHN BALLANTINE and ADAMCLARK, of Zanesville, in the county of Muskingum and State of Ohio, haveinvented a new and useful Machine for Drying Flour and other FinelyDivided Substances; and we do hereby declare that the following is atrue and exact description.

v The nature of our invention consists in the use of a cylindricalsegment, closed by caps at each end, except a passage for steam, and bya plane, covering the chord of the segment, used for the drying of flourand other finely divided substances, the drying agent being appliedunder the'plane, along which the flour or other substance to be dried,passes.

To enable others, skilled in the art to make and use our invention, wewill proceed to describe its construction and operation. The material weuse in its construction is metal.

Figure I in the accompanying drawing represents in perspective themachine entire. A, represents the cylindrical segment, of any length andany chord, closed by a cap at D, and closed also at the other end in thesame manner, except a passage for steam. The chord of the segment isclosed by a plane, as shown at H, Fig. II, with flanges or guards onboth sides and one end, of sufficient elevation to retain the flour orother substance to be dried in its passage along the plane from a to 0,Figs. I and II. The flanges are represented by B in Figs. I, II and III.The plane may be constructed toward 0, as in Fig. II.

Fig. II represents, but not in perspective, the plane.

Fig. represents, but not in perspective, a cross section of the machineat G, Fig. I.

The flour or other substance to be dried is let on to the plane at a,Figs. I and II, that end of the plane being sufliciently elevated abovethe other to cause the substance dried to pass ofi by gravity at c, Fig.II, which projects beyond the segment, as in Fig. I. The steam may beobtained in any known manner and is let into the closed segment at ahole perforated for that purpose at or near G, Figs. I and III, on theunder side and at or near the more depressed end of the machine, andpasses oil at F through pipe E. Pipe E is shown in Figs. I and II and isfirmly attached to the more elevated end of the segment and machine asthere represented.

hat we claim as our invention and Wish to secure by Letters Patent is--The use, for the drying of flour and other finely divided substances, ofa cylindrical segment, of any length and any chord, closed at the endsby caps, and along the chord by a plane, except a passage through theclosed segment for the drying agent, as herein described, the dryingagent being applied with scribed, the drying agent being applied withinthe closed segment, under the plane, and the flour or other substance tobe dried passing along the plane.
